    通过远程消除氢化物实现C–H功能化:钯催化邻酰基苯酚脱氢为类黄酮
    摘要:
    尽管人们早就知道贫电子的C–H键与碱形成碳阴离子的去质子化并广泛用于有机合成中,但从富电子的C–H键与碳阳离子或部分碳阳离子的氢化物消除是引入亲核试剂的一个重要方法。勘探面积相对较少。在这里,我们报道邻酰基苯酚的羰基β-C(sp 3)–H键氢可被分子内酚羟基取代形成O杂环,然后将O杂环脱氢成类黄酮。在不添加氧化剂和不牺牲氢受体的情况下,Pd / C催化级联反应。

  • An Enolate‐Structure‐Enabled Anionic Cascade Cyclization Reaction: Easy Access to Complex Scaffolds with Contiguous Six‐, Five‐, and Four‐Membered Rings
    作者:Tomas Javorskis、Ieva Karpavičienė、Arminas Jurys、Gustautas Snarskis、Rita Bukšnaitienė、Edvinas Orentas

    AbstractCatalyst‐free addition of ketone enolate to non‐activated multiple C−C bonds involves non‐complementary reaction partners and typically requires super‐basic conditions. On the other hand, highly aggregated or solvated enolates are not reactive enough to undergo direct addition to alkenes or alkynes. Herein, we report a new anionic cascade reaction for one‐step assembly of intriguing molecular scaffolds
    摘要酮烯醇化物与非活化的多重 C-C 键的无催化剂加成涉及非互补反应伙伴,通常需要超碱性条件。另一方面,高度聚集或溶剂化的烯醇化物的反应性不足以直接加成到烯烃或炔烃上。在此,我们报告了一种新的阴离子级联反应,用于一步组装具有连续六元环、五元环和四元环的有趣分子支架,代表正式的[2+2]烯醇-丙二烯环加成。反应在非常温和的条件下进行并具有优异的非对映选择性。更深入的机理和计算研究揭示了环酮中间体中异常缓慢的质子转移现象,并解释了特殊的立体化学结果。

  • Synthesis and quantitative structure-activity relationships of antiallergic 2-hydroxy-N-(1H-tetrazol-5-yl)benzamides and N-(2-hydroxyphenyl)-1H-tetrazole-5-carboxamides
    作者:Roger E. Ford、Phillip Knowles、Edward Lunt、Stuart M. Marshall、Audrey J. Penrose、Christopher A. Ramsden、Anthony J. H. Summers、Joyce L. Walker、Derek E. Wright
    DOI:10.1021/jm00154a019
    日期:1986.4
    The synthesis and antiallergic activity of a series of 2-hydroxy-N-1H-tetrazol-5-ylbenzamides and isomeric N-(2-hydroxyphenyl)-1H-tetrazole-5-carboxamides is described. A relationship between structure and intravenous antiallergic activity in the rat passive cutaneous anaphylaxis (PCA) test has been established using a Hansch/Free-Wilson model and used to direct studies toward potent derivatives. The contribution of physicochemical properties to activity is discussed. One member of this series, N-(3-acetyl-5-fluoro-2-hydroxyphenyl)-1H-tetrazole-5-carboxamide (3f), which was selected for further evaluation, has an ID50 value of 0.16 mg/kg po and is 130 times more potent than disodium cromoglycate (DSCG) on intravenous administration.
